Between the Stars

While exploring on the Saturnian moon Rhea, Derek Kuroda discovers the first alien artifacts found in more than a century of space exploration. Tests on the enigmatic object suggest that they are either energy packs or weapons. One thing is certain: they are sources of immense power. And so Kuroda joins forces with Sieglinde Kornfeld-Taggart, whose scientific skills and inventive genius helped to form the Island Worlds group of orbiting colonies. Following what had at first seemed a successful Asteroid Belt Rebellion, Liberty has somehow become no more than a word in the Belt as well as on Earth-so the plan is to use the newfound power of the artifacts to launch dozens of asteroid worlds to freedom among the stars. But repressive elements throughout the Solar System are just as intent on stopping them...Eric Kotani is the pseudonym of a noted physicist. John Roberts is a well-known science fiction writer.
